Lewis, Beverly Hills, Calif., assignor to The Patent and Licensing Corporation, New York, N. Y... a corporation of Massachusetts Application November 4, 1948, Serial No. 58.226

This invention relates to shipping containers for rope, wire, hose and like materials which are commonly packaged in coiled or reeled form and is more particularly concerned with such containers made of corrugated or solid fiberboard, boxboard, or similar strong, lightweight, foldable sheet material.

Containers which have been proposed for coilable material such as rope, have generally involved a complicated structure, requiring, for example, the assembling of two or more independent and seprrately formed elements. Prior attempts to simplify the construction of the container have resulted in structures which either provide little or no protection for the packaged material or are of such a nature that the material to be packaged must be separately coiled or reeled before it can be placed in the container.

It is en object of this invention to provide a container for coilable materials which is simple in construction, is adapted for use in reeling the material to be packaged and which provides adequate protection for the packaged material.

It is a further object of the invention to provide a container of the character'indicated which may be formed from a single blank of foldable material.

According to the invention I, provide a container for coilable material from a single blank of strong flexible material which is suitably cut and creased to form, when assembled, a hollow core having arm-like extensions which are adapted to encircle or embrace the coiled mate rial and thereby to protect it and hold it securely in place. I

The core of the container is adapted to be slipped over a reeling mandrel and to receive the material to be packaged while being reeled on the core.

Other features and advantages of the invention will be apparent from the following description 3 Claims. (Cl. 206-5 9) and from the accompanying drawings in which.

Fig. 1 is .a view in perspective of an embodiment of the invention containing a coil of rope.

Fig.2 is a plan View of the blank from which the container shown in Fig. l is formed. r

Fig. 3 is a top-elevation of the blank shown in Fig. 2, partly assembled and ready to receive the Fig. 6 is a plan view of another embodiment of the invention.

Fig. '7 is a planview of a blank forming another embodiment of the invention.

Fig. 8 is a plan view of the blank shown in Fig. 7 in assembled form.

Fig. 9- is a sectional view along the line 9-9 of Fig. 8.

Fig. 10 is a plan view of a modified form of the container of the invention, and

Fig. 3.1 is a plan view of another embodiment of the invention.

Referring to the drawings, and particularly to Fig. 2, the numeral l2 designates generally a blank which has been cut and scored or creased to permit fashioning of a container embodying my invention. The blank I2 may be formed from flat sheets of corrugated fiberboard, solid fiberboard, boxbo-ard or other strong, lightweight, foldable sheet material.

The blank !2 comprises a body portion formed by marginal body panels Ma and His and an intervening panel Mb, flexibly joined along crease lines 85. A body flap It is flexibly joined to body panel 'l lc along crease line ll. Extending outwardly from the sides of the body panels are side panels l8 and 26, joined to the body panels along crease lines 2| and end flaps 22 and 2 are flexibly joined to side panels l8 and 25 alon crease lines 25. Cuts 2e extend laterally from the crease lines 2| to the outer free edges of the blank.

Referring to Fig. 3, the core of my container, which is adapted to receive, during the reeling operation, thematerial to be packaged, is formed by bending the body portion along crease lines l5 and securing the body flap It to the inner surface of body panel ltd, as by staples 28 or by a suitable adhesive. in reeling the material to be packaged, side panels ltand 20 are bent at right angles to the body panels along crease lines ii. In this form the partly assembled container is adapted to be slipped over a reeling mandrel 35 and the rope or other coilabl'e material 32 reeled directly around the hollow triangular core formed by body panels Ma, Mb, lie, and flap it.

Referring particularly to 1 and Fig. 5, when the 'coilable material has been reeled about'the core of the container, the end flaps 22 and 24 are overlapped by bending them inwardly on crease lines 25 at right angles to the side panels iBand one another, as by staples 33 or suitableadhesive. When completely assembled, as shown in Fig. 1, the container of the invention holds the coiled material securely in place. The side panels and endflaps at each end of the central'core thus encircle or embrace the coiled material atspaced To prepare the blank for use intervals. This provides protection for the material during shipment and storage. It will be apparent that my container can advantageously be shipped as a single flat blank, thereby occupying a minimum of space, and may be quickly assembled for use either by hand or by suitable machinery.

The end flaps 22 and-24 may be provided wlth integral locking means whereby the final assembly of the container may be effected without the; use of staples, adhesives or other extraneous se-, curing means. Referring particularly'to Fig. 7, the outer edges of end flaps 22 areprovided with locking tabs 35 flexibly joinedthereto, alone" crease lines 36. Complementary; slots 3-1- are'pro-: vided in end flaps 24 adjacent the crease lines 25. Referring to Figs. 8 and" 9, when the end flaps 22 and 26 are overlapped, lockingtabs' 35.

slip through slots 31, thereby securely holding end flaps 22 against end flaps 24.

While in the embodiments of theinvention above-described, the core-forming body portion is formed by three integral body panels and an integral body flap, which, when assembled, provide a triangular core for the container, the invention includes structures having four, five, six or more body panels. Fig. illustrates an embodiment of the invention having a square core formed by four body panels, 49a, 40b, 66c, and MlaLand a body flap 41,.and having side panels 42 and end flaps 43. The end flaps 43 are secured by locking tabs 44. Fig. 11' illustrates an embodiment of the invention having a pentagonal core formed by body panels 55a, 45b, 45, 45d, and45e and abody fiap 46 and having side panels 41 and end flaps 68.

A still further embodiment of my invention is illustrated in Fig. 6. In this embodiments. hexagonal core is formed by six body panels 50a, 50b, 50c, 56d, 58c, and SM and a body flap 5| overlapping and securedto body panel 5011. It will be observed that only every other body panel is provided with side panels and end flaps. Thus body'panels Sea, 580, and 58a are provided-with side panels 52 and end flaps- 53' whereas body panels 59b, 50d, and 59f have free sides.

While my container is advantageously adapted to receive the material to be packaged in the course of the reeling operation", as described hereinabove, it will be apparent'that it may" also be used, if desired, for packaging previously coiled materials. For example, after the core-of the container has been assembled and be'fore'the side panels'lil and 2t havebeenbent into the position shown in Fig. 4, a previously formed coil'of'rop'e', rubber hose, or the like may be readily slipped over the core. The side panels'may then'bebent inwardly and the end flaps 22 and 2'4'overlapped to embrace the coil;

It will also be apparent toth'ose skilled the art that various changes and modifications may be made without departing from the spirit or scope of the invention as defined in theappended claims and it is therefore intended that all mat ter contained in the foregoing. description and'in the drawings shall be interpreted as illustrative and not in a limiting sense.
